SPECIFICATION forming part of Letters Patent N0. 755,036, dated. March22, 1904. Application filed January 23, 1902. Serial No. 90,911. (Nmodel.)

To aZZ whom it may concern:

Be it known that I, ARTHUR OBRIEN, a citizen of the United States, and aresident of the city of Chicago, in the county of Cook and State ofIllinois, have invented'certain new and useful Improvements in AutomaticSiphon- Valves; and I do hereby declare that the following is a full,clear, and exact description thereof, reference being had to theaccompanying drawings, and to the letters of reference marked thereon,which form a part of this specification.

This invention relates to improvements in automatic siphon-valves, andis shown for convenience embodied in a basin cook or faucet soconstructed as to close automatically against the pressure of theprovided with means for regulating its operation to any desiredpressure. Heretofore many different self-closing valves havebeenconstructed, some of which are objectionable owing to the difliculty insatisfactorily packing the same to insure successful operation.

The object of this invention is to provide an automatic andperfectly-regulable valve so constructed as: to entirely avoid thenecessity for packing of any kind whatsoever.

This invention consists in matters more fully described, and pointed outin the appended claims.

As shown in the drawings, Figure 1 is a vertical section of a deviceembodying my invention, showing the same embodied in a basincock. Fig. 2is an enlarged front elevation of a valve-cylinder within which thevalve seats.

Fig. 3 is a section taken on line 3 3 of Fig. 1.

As shown in said drawings, A indicates the faucet-body provided with thenozzle (6 and divided horizontally into an upper and a lower chamber'Aand A respectively, by an apertured partition 0 and anupwardly-extending relatively short sleeve (0 registers with saidaperture. Concentric with the sleeve a is the upwardly extending valvecylinder (0", of greater length, which is apertured on the side adjacentto the nozzle, as shown in Figs. 1 and 2, the upper wall of saidaperture beingdownwardly and outwardly inclined.

B indicates the valve closure, as shown,

I ripheral flange B fluid to be controlled and depending flange b onsaid countersunk'on its lower end to receive the washer I) and providinga flange b, which extends below said washer and when the valve is closedfitting closely outside of the sleeve (0 A valve-stem rigidly secured onthe closure extends upwardly within the valve-cylinder (6 and isprovided with a peripheral flange b integral therewith, which fitsclosely within said valve-cylinder a and is so located that when thevalve-closure is in position to close the valve said flange liesslightly above the top of the opening to the valve-cylinder. Above thevalve-cylinder a is provided the deflecting-guide B, also integral withthe stem and provided with a downwardly-extending pewhich for a part ofits circumference fits closely around the valve-cylinder a The upperends of the stem (indicated by b") is screw-threaded.

The upper end of the valve-casing is open to permit the insertiontherethrough of the valve-stem and parts thereon and is provided withscrew-threads, as shownin Fig. 1, adapted to engage the complementalinterior screwthreads of the cap B A central angular aperture isprovided in said cap adapted to receive the adjusting-shaft 6 which isscrewthreaded at its lower endcomplementally with andto engage thescrew-threaded end of the stem 6.

v C indicates a strong coil-spring which engages on the inner side ofthe cap and onthe top of the deflecting-guide B and acts to hold firmly.the valve seated against the pressure of the fluid.

D indicates an operating-lever pivoted on the adjusting-shaft above thecap and proin its closed position videdwith a ball, roller, or otherantifrict10n I device permanently secured thereto, which affords afulcrum for the operation ofsaid lever in lifting the valve-closure.

The operation is as ing adjusted to withstand the desired pressureagainst the tension of the spring C, when the valve-closure is lifted bythe lever the fluid jets outwardly through the aperture in thevalve-cylinder a into the nozzle. If the valvethe downwardlyclosure actsto declosure is lifted but slightly,

follows: The valve be-' fleet the fluid downwardly toward the orifice,preventing any portion thereof finding its way upwardly in the chamberA. Obviously the same effect is produced at any position of thevalve-closure less than the vertical height of the aperture in thevalve-cylinder (4 hen the valve-closure is elevated to its greatestheight, or, in other words, to the maximum capacity of the valve, thedownwardly-hr clined upper wall of the aperture serves to deflect'thefluid, as before described, and by causing a downwardly-directed currentcon-' centrates the flow in the direction of the orifice, or, in otherwords, in the line of least resistance. The flange if, fitting closelywithin the valve-cylinder a, serves as adeflector and provides anannular chamber in the top of the casing, in which, as well as in theupper part of the chamber A, a partial vacuum is pro; duced, causing aninflow of air from above and preventing upflow of the water or otherfluid passing through the valve. Said flange also serves as a guide. Thedeflecting-guide B also acts to direct any fluid finding its way pastthe flange b downwardly to the spout-orifice and acts to hold thevalve-stem from unscrewing from the adjusthug-shaft by means, as shown,of vertical guides a", integral with the casing, engaging incomplemental grooves in the flange B", of said deflector.

In adjusting the valve to reduce or increase its resistance to pressurethe cap His screwed up or down on the top of the casing, thereby varyingthe tension on the spring and at the same time adjusting the adjlisting-shaft on the valve-stem, said cap and adjusting-shaft beingsimilarly threaded to insure equal vertical adjustments.

While Ihave shown the invention embodied in a basin-cock, it is obviousthat valves constructed as described may be embodied in many differentforms and devices and used for any purpose in which it is desired toemploy a pressuieoperated valve without packing, and I do not desire tobe restricted or limited to the specific embodiment of my invention asherein shown,

Obviously the details of construction may be varied without departingfrom the principles of my invention.

I claim as my invention- 1. In a valve, the combination with atwochambered valve-casing, of a valve seat tl'irough which the chamberscommunicate, a valve-closure seated thereon, a peripheral flange on thevalve-closure seating below the same, a valve-cylinder inclosing thevalve closure and seat, and apertured adjacent to the discharge-orificeand a deflector movable with the valve-closure and acting to directfluid toward the discharge-orifice.

2. In a valve, the combination with the easing comprising an inner andan outer chamher, a passage through which the-chambers communicate, avalve-closure seated to close said passage, a valve-cylinder integralwith the casing surrounding said valve-closure, and provided with anaperture directed toward the valveorilice and so formed as to convergethe fluid therein and adeflectorlocated above said aperture and actingto deflect the fluid toward the orifice.

3. In a valve, the combination with a valvecasing having an unobstructeddelivery, of a valve seated therein and comprising a valveseat, avalve-closure therefor, a peripheral flange on the valve-closureextending below the valve-seat, a valve-cylinder inclosing the valveseat and closure, a deflecting-guide movable with the valve-closure andengaging over the valve-cylinder, and an aperture in the valve-cylinderdirected toward the orifice and formed to converge the flow into theorifice.

4. The combination with a two-chambered valve-casing, of a sleevedpassage connecting the chambers, a valve-closure seated thereon, aflange thereon extending below the top of the sleeve, a valve-cylinderinclosing the valveclosure and provided with an aperture opening towardthe orifice and formed to converge the fluid thereinto, adeflecting-guide within said valve-cylinder located normally above saidaperture and a guide-deflector located normally above the valve-cylinderand held from rotation by parts on the casing.

5. In a valve of the class described, a casing comprising an inner andan outer chamber, a

valve-closure therein, deflecting means acting to converge the flow intothe discharge-orifice, an upwardly-extending stem on the valve-closure,an adjustable cap on the casing, an adjusting-shaft adjustably engagedon the stem, a spring engaged in the cap and acting to hold the valveclosed, said cap and adjusting-shaft being adapted for simultaneousadjustment,

to vary the tension of the spring.

6. In a valve, the combination in a casing comprising inner and outercommunicating chambers, the outer having an unobstructeddelivery-orifice, of a valve-closure in the passage bctween thechambers, deflecting means adjacent thereto acting to converge the flowinto the discharge-orifice, a stem on said closure, a cap adjustablysecured on the casing and forming the top of the outer chamber, anadjusting-shaft passing through the cap and adj ustably engaging thestem, a spring engaging against the cap and acting to close the valve,means on the adjusting-rod for lifting the valve-closure, and means foradjusting the cap and adjusting-shaft simultaneously to vary the tensionof the spring.
